The SEPIA cross-platform-clients can access the RESTful Assist-API directly and exchange data in JSON format (e.g. for user authentication) or connect to the SEPIA chat-server to send and receive messages.
SEPIAs running on this server can log-in to the WebSocket chat-server the same way a user does and communicated via channels with multiple users (or devices) at the same time.

The SEPIA Assist-Server operates as your own cloud-service and is designed to work the same way no matter if you run it on a Raspberry Pi for a small group of users in a private network
or when you host it on multiple servers for a larger company network.
